Jeep V-6 engine

Which V6 and what year and what problems??

2011 Jeep V-6 with 96K and no problems

I'd wait for the new diesel that is coming in 2018 I think.

Exactly.

To my knowledge there have been three V6's in Jeeps. One is the old 90 degree Buick V6 that was used in the '60's and early '70's. Think it was called the Dauntless V6...doubt if it is that one....had a good reputation and was used too many years ago.

In this century, there was the V6 (think it was a 3.8 liter) that was based on the Mopar 4.7 liter V8...with two cylinders lopped off and the current V6 (Pentastar V6) that is used in a number of cars and light trucks (including Jeep ) that is in 3.2 and 3.5 liter sizes.

Starting in 2012, Jeep wranglers started using the 3.6 Pentastar V6 engines. The early Pentastars did have some head problems. The heads were replaced under warranty and the heads were redesigned. I have two Jeep Wranglers (2014 and a 2015). Although I don't have many miles on them yet the engine is very strong and smooth. They also use these engines in the Ram 1500 trucks and there are many on the road with over 100K miles. It's a very good engine.

In the early 80's until 87 the used a Chevy or Buick 4l V-6 (it was a dog). In the early 2000's they went to the 3.7l V-6, good power, but you had to change oil all the time(it would start to gum up.) Lost ours when it spun a bearing. And now they have the 3.6l Pentastar

Owned two and no problems with either.

Only 2 V-6's recently. The old 3.8 which was the old minivan motor, absolutely zero problems but underpowered. And the current 3.6 Pentastar. Another good motor. Not sure of any problems. But it is a strong motor.

We bought our 2014 Grand Cherokee V6 8/30/13. We only have 25,000 miles with no problems. Only regret I have is I didn't get the hemi.:)

Jeep didn't use a Buick engine of any kind in the early '80's till '87 time period.

However during those years, they did use the small 60 degree , Chevy 2.8 liter V6, which is quite a bit smaller than a 4 liter as you indicated . If you mean by 'a dog' you're referring to lack of power...all it put out in the Jeep version was 115 hp, that was with a carburetor.

You're correct, not a lot of power, but not really untypical of any engine of that small cubic inch capacity, during that era.
